Samesurf Wins Federal Circuit Ruling Upholding Core Co-Browsing Patent

May 27, 2026
Samesurf has secured a Federal Circuit Court ruling affirming the validity of its foundational synchronized browsing patent, following earlier success before the Patent Trial and Appeal Board.

Samesurf has obtained a decisive legal victory at the United States Court of Appeals for the Federal Circuit, announced in a press release. The court issued a Rule 36 judgment on April 7, 2026, affirming the validity of Samesurf’s U.S. Patent No. 9,483,448, which covers methods for synchronized browsing on a host device.

The ruling follows a 2024 decision by the Patent Trial and Appeal Board that upheld all 16 claims of the same patent. The patent, with a priority date of May 20, 2010, underpins the technology used in co-browsing and real time collaboration systems.

These judicial outcomes are connected to Samesurf’s ongoing patent infringement lawsuit against Intuit, filed in the Southern District of California in 2022. The company stated that the affirmed patent forms the basis of its zero-install synchronized browsing framework, which is used across multiple collaborative software products.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
